History of TB disease.
History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine.
Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
QuantiFERON® TB Gold positive test result.
History of medically confirmed autoimmune disease.
Administration of immunoglobulins and/or any blood products within the 3 months preceding the first dose of study vaccine or planned administration during the study period.
History of any reaction of hypersensitivity likely to be exacerbated by any component of the vaccine.
Pregnant or lactating female.
Female planning to become pregnant or planning to discontinue contraceptive precautions.

E.5 End points |
E.5.1 | Primary end point(s) |
Evaluation of Interferon gamma (IFN-gamma) secretion in serum; determined by IFN-gamma-specific antibody concentrations as measured by ELISA.
Evaluation of cell mediated immunogenicity (CMI) responses with respect to components of the study vaccine; determined by the frequency of M72-specific CD4+/CD8+ T cells per million cells identified after in vitro stimulation, as expressing at least 2 immune markers among IL-2, TNF-alpha, IFN-gamma, CD40L, IL-13 and IL-17 and determined by the frequency of M72-specific CD4+/CD8+ T cells per million cells identified after in vitro stimulation, as expressing any combination of immune markers among IL-2, TNF-alpha, IFN-gamma, CD40L, IL-13 and IL-17.
Occurence of Serious Adverse Events (SAEs)
Occurence of solicited local and general Adverse Events (AEs).
Occurence of unsolicited Adverse events (AEs)
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
INF-gamma secretion in serum:Prior to dose 1 (Day 0), post dose 1 (Day 30), post dose 2 (Days 31, 37, 40, 44 and 47).
Cell mediated immunogenicity:Prior to dose 1 (Day 0) and post dose 2 (Day 60).
